1、 2022年职称英语等级考试理工C级模拟试题(三)3El Nino (厄尔尼诺现象)While some forecasting methods had limited SUCCESS predicting the 1997 E1 Nino a few months in advance，the Columbia University researchers say their method call predict large E1 Nino events up to two years in advance.That would be good news for governments，f
2、armers and others seeking to plan for the droughts and heavy rainfall that El Nino can produce in various parts of the world.Using a computer the researchers matched sea-surface temperatures to later El Nino occurrences between 1980 and 2022 and were then able to anticipate E1 Nino events dating bac
3、k to1857, using prior sea-surface temperatures.The results were reported in the latest issue of the journal Nature.The researchers say their method is not perfect, but Bryan C.Weare.a meteorologist at the University of California, Davis，who was not involved in the work，said it“suggestsE1 Nino is ind
4、eed predictable.”“This will probably convince others to search around more for even better methods.”said Weare.He added that the new method“makes it possible to predict El Nino at 1ong lead times.” Other models also use sea-surface temperatures, but they have not looked as far back because they need
5、 other data，which is only available for recent decades，Weare said.The ability to predict the warming and cooling of the Pacitic is of immense importance.The 1997 El Nino，for example，caused an estimated$20 billion in damage worldwide，offset by beneficial effects in other areas，said David Anderson，of
6、the European Centre for Medium.Range Weather Forecasts in Reading England.The 1877 El Nino，meanwhile，coincided with a failure of the Indian monsoon and a famine that killed perhaps 40 million in India and China。prompting the development of seasonal forecasting，Anderson said.When El Nino hit in 199 1
7、 and 1997.200 million people were affected by flooding in China alone.according to a 2022 United Nations report.While predicting smaller E1 Nino events remains tricky.the ability to predict larger ones should be increased to at least a year if the new method is confirmed.E1 Nino tends to develop bet
8、ween April and June and reaches its peak between December and February.The warming tends to last between 9 and 1 2 months and occurs every two to seven yearsThe new forecasting method does not predict any major El Nino events in the next two years, although a weak warming toward the end of this year
